An estimate will give an indication of the order of magnitude of the answer. The decimal point determines the order of magnitude and so, if the two are in agreement, then the decimal point has been placed in the right place. However, if you did your arithmetic properly then there would be no need to do the extra calculations required for an estimate.
44/22 = 2 so the decimal point should be placed after the first digit (which is a 1).
It is placed over one length of repeating decimal digits.
Nowhere. 10000 is an integer and requires no decimal number.
Not really.If you are competent in using the basic operations of arithmetic (+ - * /) and follow the riles as these apply to decimal numbers then the decimal point will be correctly placed and finding a whole number estimate will only mean additional calculations which serve no purpose. On the other hand, if you are not that competent then how can you be sure that the whole number estimate that you find is accurate?
................................................................._0.384333 using the bar notation = 0.3843(the bar should be placed above the repeated decimal. In this case, it should be above the 2nd 3 from the decimal point.
You could try estimation to get an idea of the magnitude of the answer.
A reasonable estimate will give an indication of the order of magnitude of the number. The order of magnitude is determined by the decimal point and so knowing the order can help in placing it.
Estimating the answer helps you to know if you placed the decimal point correctly in the sum because you can quickly check if your estimated answer matches closely with the actual answer. If they are similar, it suggests that the decimal point was placed correctly. If they are significantly different, it may indicate an error in placing the decimal point.
When you multiply decimals, the decimal point is placed in the product.
44/22 = 2 so the decimal point should be placed after the first digit (which is a 1).
Where the decimal is placed you just have to bring it straight down.
The product is the answer to a multiplication.
It is placed over one length of repeating decimal digits.
